Table 2 Descriptive longitudinal characteristics of knees with medial tibia bone marrow lesion (BML) regression, progression, or no change

From: Bone marrow lesion volume reduction is not associated with improvement of other periarticular bone measures: data from the Osteoarthritis Initiative

Variable BML regression (n = 76) No BML or No BML change (n = 156) BML progression (n = 76)
  Median (Min, Max) or n(%) Median (Min, Max) or n(%) Median (Min, Max) or n(%)
BML volume change (cm3) -0.36 (-8.44, -0.14) -0.02 (-0.13, 0.03) 0.21 (0.04, 6.77)
Medial tibia paBMD change (g/cm2) 0.002 (-0.149, 0.164) -0.011 (-0.107, 0.149) -0.001 (-0.091, 0.168)
M:L paBMD ratio (change) 0.005 (-0.119, 0.291) -0.007 (-0.102, 0.091) 0.003 (-0.080, 0.410)
Medial tibia sclerosis progression 5 (7.0%) 2 (1.3%) 7 (10.0%)
